Researchers at UC Davis have also recently made headlines trying to forecast earthquakes
(Press release [ucdavis.edu]). I wonder if we're on the brink of a new understanding of earth's geophysical processes.

"We see this kind of tremor activity inside volcanoes like Mount St. Helens," Nadeau said, "but that's due to the movement of rising magma, and in the tremors we've recorded there's no evidence of volcanism and no seismic waves typical of ordinary earthquakes."

Not have earthquake warnings? If you build your state on a major fault line, you deserve what you get. Sure its all warm and everything, but you can get that in Florida, only thet have hurricanes instead.

Moral of the story: Move from California to Toronto, no hurricanes/tornados/earthquakes. Just remember to buy a jacket before you leave home.

Don't worry, California's one of those states where more people move out than move in every year. Eventually no one can afford to live in a state filled with overpriced real estate on top of a gigantic crack.

The tremors are related to the subduction of the pacific ocean under north america.

The san andreas fault is a remnant of the subduction zone, where the pacific spreading ridge has already been consumed. This ridge is still a couple hundred km offshore of vancouver island.

The deep tremors on the san andreas are probably caused by the change in strain on the system after the same tremors have occured up here. Yes, the deep tremor cycle did occur like clockwork, as predicted by the canadian pacific geoscience center a few months ago under vancouver island. Several 14 month cycles have been observed.

The weird thing about the tremors is that it represents a rebound in the subduction of the ocean plate. instead of subducting a few cm per year, in two weeks the subduction reverses by about 5cm, and then goes back to the normal.

It is thought that the changes in strain caused by all this may increase the short term chances of the next big quake hitting southwest BC by a large factor.

Anywho, go away, there's nothing truly new to see here, it may not have been observed so far south before, but it is not a discovery of a new type of geologic activity, the Canadians already documented it, which maybe the media would have realized had they bothered to look outside your borders for something other than the injustices of Iraq.
